What is the difference between an expression and an equation

Mathematics
1 answer:
Ainat [17]3 years ago
6 0

The primary difference between the two is an equals sign. An equation has a left side, a right side and an equals sign separating the sides. Equations also may have solutions. An expression, by contrast, doesn't have any 'sides' .

Which choice represents the equation of the line with a y-intercept of -5 and parallel to the line whose equation is 2y + 4x=8
Andreas93 [3]

Answer:

y = -2x - 5

Step-by-step explanation:

The slope of the given line is found by solving 2y + 4x = 8 for y:

2y =  -4x + 8, or y = -2x + 4.  The slope is -2.

We need to find the equation of a line parallel to this one and with y-intercept -5:

y = mx + b becomes, after suitable substitutions, y = -2x - 5

The area of a rectangle is x^2−4/2x in^2 and its length is (x+2)^2/2 in. What is the width in inches?
lara31 [8.8K]

Answer:

The answer to your question is  Width = \frac{x - 2}{x + 2}

Step-by-step explanation:

Data

Area = (x² - 4)/2 x in²

Length = (x + 2)² / 2 in

Width = ?

Process

1.- Write the formula of the area of a rectangle

     Area = length x width

-Solve for width

     Width = Area / length

2.- Substitute the values

     Width = (x² - 4)/2 / (x + 2)² / 2

-Simplify

     Width = (x² - 4) / (x + 2)²

-Factor both numerator and denominator

      Width = (x - 2)(x + 2) / (x + 2)(x + 2)

- Simplify

      Width = (x - 2) /(x + 2)  or Width = \frac{x - 2}{x + 2}

A table has five bowls. None of the quantities in the bowls are prime, though the last two bowls are empty. Two of the quantitie
Digiron [165]

Since two of the quantities are squares and the sum of all of three is equal 21, then the possible values of those two quantities are: 1,4,9,16

Let's consider each possibility

1 and 4

21-1-4=16, but 16 is also square and there can be only two square so NO

1 and 9

21-1-9=11, but 11 is prime, so NO

1 and 16

21-1-16=4... 4 is a square ,so NO

4 and 9

21-4-9=8 , 8 is not prime and not a square, so YES

4 and 16

21-4-16=1, but 1 is a square ,so NO

9 and 16

9+16=25>21 so.. NO

<u>Therefore, the amounts in the first three bowls are 4,8,9.</u>
